Title: Balance point Brodak Skyraider
Post by: Jack R. Dock on April 27, 2009, 01:48:27 PM
Finishing up a Brodak AD Skyraider (my first Carrier plane) and was wondering if anyone had an idea of where the balance point might be?  Its a nice kit for a "mash cut" but neither the instruction manual or the plans tell you where the balance point is.  I have put every thing on it to check the balance and it appears to be right on the leading edge of the wing.  That's a bit nose heavy by my standards but this is my first one and I know they fly a bit different than I am use to in the "slow mode".  Little help some one with experience (how about it Doc?).

When I built the Brodak Mauler I built it as close to box stock as I could.   Never chacked the balance point.  Second flight on the plane with Fox 35 Stunt I put it thru the pattern.  When I got the Brodak 25 I put it on the plane to finish breaking it in.  It wound up being Emmy's plane until Tulsa last year. 

Ever since I started in this crazy hobby, every thing read said no more than 25 % of the chord for the balance point.  The P-39 is the first plane that came out so nose heavy it would not turn a sharp corner.  Flite Streaks were quick on controls even when a little nose heavy.  Of course they had Fox Combat Specials on them. 

Try the first flight and then adjust accordingly.  DOC Holliday
